SPECIFICATION forming part of Letters Patent No. 716,384, dated December23, 1902.

Application filed October 28, 1901. Serial No. 80,318. (No model.)

To all whom it may concern:

Be it known that I, MASOHIL D. CONVERSE, a citizen of the United States,residing at New York, borough of Manhattan, in the county of New Yorkand State of New York, have invented certain new and useful Improvementsin Miter-Boxes, of which the following is a specification.

My invention relates to miterboxes in which a radially-swingingsaw-guide is socured by means of a bracket and pivotal post to anupright right-angular memberof the box proper or, more definitely,relates to what are termed miter-box attachments; and my I 5 inventionis comprised in the several devices,

combinations, and arrangement of parts hereinafter particularlydescribed and claimed.

The objects of my invention are to provide an accurate, convenient,durable, and inexzo pensive miter-box complete or as an attachmentreadily carriedin kit.

In the drawings, Figure 1 is a plan view of my invention complete,showing its construction and operation in part. Fig. 2 is a frontelevation further showing construction and operation thereof and with aback-saw a (sectionized) in place, hereinafter referred to. Fig. 3 is aleft-hand side View of the swinging saw-guide, and Fig. 4 is a sectionalplan view thereof on line y 3/ of Fig. 3, both removed from the pivotalpost. Fig. 5 is a rear side elevation of the bracket and its cylindricalpivotal post detached from the box proper, all which show theconstruction, ar-

rangement, and details of my invention,which I will now proceed todescribe.

Like letters indicate corresponding parts throughout the severalfigures.

A is an upright member (usually of wood) one edge of which is secured toa horizontal floor or base B, (also usually of wood,) so as to be in afixed and accurate right-angular relation to the latter. Thisupright iscut away between the points a: w and z in order that the bracket 0(clearly shown in Fig. 5) may be mounted upon the stepped portionthereof by screws for reception of which the holes 1) b b are provided.

The pivotal post D, which is cylindrical, is

secured rigidly in a socket in the base of the bracket in a positioncentrally the longitudinal plane of the upright A. (See Fig. 1.) Thisbracket has a flange 0, which projects forward from its uppermost edge,and the under face cl of the same is at exact right angles to thepivotal post D, while the latter is socketed, so as to be perfectly inline with the vertical longitudinal center of the upright A.

E (see Fig. 2) is a lug or block on theinner 6o face of the bracket A.In a slot cut slantingly in both this lug and in the flange 0,respectively at e 6 and which are vertically in exact alinement with thelongitudinal center of the post D, a tapered key K, having a V- shapededge f, is fitted to slide snugly up and down and by means of a slot 9and pin his kept from being entirely removed. The sawguide is composedof two quite similar halves G G riveted together at t' t', and by thinwashers at j j or otherwise are separated sufficiently-to take the bladeof the saw, as shown by a in Fig. 2. These halves are also formed so asto leave a clear space Hfor the back a of a back-saw and to formshoulders 7o 70 70 70 hereinafter more particularly referred to. Thehalf G is provided with an enlargement I at the forward lower corner onthe lateral side and at the same place with a laterally-extended segmentJ, through both which vertically a hole is bored perfectly parallel tothe surfaces that act as guides to the saw and at perfect right angles,too, to the plane of the shoulders 7c 7c 70 7a. In the periphery of thesegment J a number of V-shaped notches or graduations are cut atpositions representing the most commonly used angles in carpentry andwoodworking, which I usually indicate by the first letter of the namestherefor. As shown, the notch indicated by 0 R (see Figs. 1 and 4) is atexact right angles to the saw-guiding faces of G and G and like Wise toa line drawn from the laterally-projecting points Z m. There is a slot avertically in the enlarged part I, and transversely 5 thereof athumb-screw o is arranged laterally of the vertical plane of and topinch the pivotal post D to hold the swinging saw-guide in any positionas to height or angle which may be required.

It frequently happens that some arbitrary angle (not indicated on thesegment) is to be IOO cut. I therefore have provided the two projectingpoints Z and m, which parallel the saw-guiding faces, so that by meansof abevel T-square, as shown by dotted outlines in Fig. 1, the guide canbe set and fixed firmly with the thumb-screw 0.

In Fig. 2 the saw-guide is shown raised up a short distance on thepivotal post D and secured by the thumb-screw. This position illustratesthe operation of my invention when a tenon is to be cut or a cut is tobe made only partially through and to a predetermined depth, as in ablock, (indicated in this figure by the dotted outlines 19,) for thesaw-back a then comes into contact with the shoulders 70 70 k 70stopping its further action. For all except work of this character acommon handsaw may be used with equal facility.

The slotse and 6 respectively, in the lug E and flange 0 are of suchdepth that the line of the V edgefof the key K inclines slightly at thetop away from the post D, so that when the saw-guide is to be set at oneof the indicated angles and at an elevated position on the post the keyK will wedge sufficiently to retain the saw-guide up on the post withoutnecessity of tightening the thnm b-screw. (See Fig. 2.)

At P in the lowermost arm of the part G there is a bend and return toleave a hole or opening, so that convenient sighting of the saw-teethand any mark upon the edge of the.

Wood to be cut may be had.

It will be understood by those skilled in the art that by detaching thebracket 0 from the box proper my invention may be carried as anattachment to be mounted when needed.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a miter-box, a bracket having slanting slots, a tapered inclinedslidable key to operate in said slots, and a pivotal cylindrical post,in combination with a saw-guide pivoted on said post and provided with anotched or graduated segment for engagement with said key.

2. In a miter-box, a bracket having slanting slots, a tapering inclinedslidable'key to operate in said slots, and a pivotal cylindrical post,in combination with a saw-guide pivoted on said post provided with anotched or graduated segment for engagement with said key and twolaterally-projected setting or gaging points on a lateral side of saidsawguide having their respective extremities equidistant from thesaw-engaging surface.

3. In a miter-box, a bracket having slanting slots, a pivotalcylindrical post, a tapered slidable key to operate in said slantingslots provided with an inclined V-shaped edge, in combination with asaw-guide pivoted on said post and provided with a notched or graduatedsegment for engagement of the V edge of said key.

I. In a miter-box, a horizontally-swinging saw-guide provided with anotched or graduated segment, in combination with a recessedsighting-hole in the lowermost left-hand arm thereof.

5. In a miter-box, a cylindrical pivotal post and ahorizontally-swinging, vertically-adjustable saw-guide, in combinationwith a screwclamp arranged transversely and laterally of the verticalplane of said post in a laterally-extended bifurcated member.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
